Unraveling the Secrets of Prochlorococcus’ Iron-Binding Protein
Researchers at the University of Southampton, led by Ivo Tews, uncover the secrets behind Prochlorococcus’ ability to thrive in low-nutrient waters through the study of its iron-binding protein, FutA. The study, published in the Proceedings of the National Academy of Sciences, utilized advanced structural biology techniques to reveal how FutA can accommodate iron in two oxidation states, enhancing the cyanobacterium’s efficiency in nutrient-poor environments. Neutron crystallography and optical spectroscopy measurements were key in determining the charges of amino acid side chains and tracking iron oxidation states, with Diamond Light Source’s I24 beamline playing a crucial role in capturing real-time structural changes in FutA.
The Role of Crustal Carbonate Build-Up in Earth’s Oxygenation
